A collaborative procurement approach can change the relationship between the client and supply chain by encouraging earlier communication and greater involvement. Understanding collaborative procurement in construction helps explain how contractors and suppliers may contribute knowledge before construction begins. Their input can influence design development, sequencing, materials, and construction methods. This can create opportunities to address practical issues earlier. Effective collaboration depends on trust, transparent information, and clearly established processes.
